REST/API running for Python/Flask applications using Gunicorn & nginx
This is a shell container & won't run stand-alone.
It is designed to run read-only, but if you do want to run it read-only, you
should add RUN python3 -m compileall /opt/python/ into your Dockerfile
after you have copied all your code into /opt/python so the python byte-code
can be created & stored in __pycache__, as this can't be done at run-time when read-only!!!
All you need to do is install your python/flask application into /opt/python with a tiny program called
wsgi.py that looks something like this
#! /usr/bin/python3
from you_app_main_file import application
if __name__ == "__main__":
application.run()
You may also want to customise nginx.conf
If you have a few python/flask micro-services, putting all the common parts into a parent container should be more efficient.
